Wafer Map Analysis Diagram
This sample depicts a wafer map diagram, a tool used in semiconductor manufacturing. It shows both the oxide thickness and usability of each die (chip) on the wafer via a tool tip, and the overview viewing modes can be toggled at the top right of the diagram. Enter the desired die dimensions and wafer size to calculate the die per wafer and see generated mock data.
It uses the PackedLayout extension to fit several die nodes into an optimal circle shape, and a Group to create the wafer border. The status of each die is stored in the node data array, and its color is determined by a corresponding data binding.
GoJS Features in this sample
Custom Layouts
GoJS allows for the creation of custom layouts to meet specific needs.
There are also many layouts that are extensions -- not predefined in the
go.js or go-debug.js library, but available as source code in
one of the three extension directories, with some documentation and corresponding
samples. More information can be found in the
GoJS learn pages.
GoJS Extensions
GoJS can be extended in a variety of ways. The most common way to change the standard behavior is to set properties on the GraphObject, Diagram, CommandHandler, Tool, or Layout. But when the desired property does not exist, you might need to override methods of CommandHandler, Tool, Layout, Link, or Node. Methods that you can override are documented in the API reference. Various features of GoJS can be overriden, either by replacing a method on an instance (a feature of JavaScript) or by defining a subclass. You should not modify the prototypes of any of the GoJS classes.
In addition to our samples, GoJS provides an
extensions gallery, showcasing the creation of custom tools and layouts. Those classes and samples are
written in TypeScript, available at ../extensionsJSM/, as
ECMAScript/JavaScript modules -- these use the
../release/go-module.js library. We recommend that you copy the files that
you need into your project, so that you can adjust how they refer to the GoJS library
that you choose and so that you can include them into your own building and packaging
procedures.
More information can be found in the GoJS learn pages.
Groups
The Group class is used to treat a collection of Nodes and Links as if they were a single Node. Those nodes and links are members of the group; together they constitute a subgraph.
A subgraph is not another Diagram, so there is no separate HTML div element for the subgraph of a group. All of the Parts that are members of a Group belong to the same Diagram as the Group. There can be links between member nodes and nodes outside of the group as well as links between the group itself and other nodes. There can even be links between member nodes and the containing group itself.
